The part of the compiler output that you posted is the end when all jobs are being terminated. It doesn't show the actual error. The errors would likely be shown somewhere above that.
Can you please paste the entire compilation output?

@r2com It looks like Qt5Core was not built. How and from where did you call configure and make?
C:/Qt/Qt57_build/qtbase/bin/uic.exe: error while loading shared libraries: Qt5Core.dll: cannot open shared object file: No such file or directory

It is amazing that this is a common post that keeps coming up. "Building Qt in MinGW64." I know I have posted about MSYS2 and its complete 32bit and 64bit devel kit for Qt (currently 5.61) and QtCreator (4.0.3) using the gcc MinGW64 toolchain (now at 6.1.0).

I, myself, prefer to focus on using Qt and not building it. I let the pros at Qt or distro builders do that. You can download MSYS2 from https://sourceforge.net/projects/msys2/ and then using pacman, the package manager, can download and install the toolchains and Qt API. Generally takes about 30 minutes to one hour to download and install the complete toolchain and Qt development kit.

I have other and more complete write-ups in the forum on this. Save some time, headaches, and get doing what you most want to do... create great code!

@SGaist Thanks! Can we access the current Wiki to change it? There is some writeup on alternate builds but they are not complete or actually very useful. I was thinking that building Qt is coming up so often that there should be forum topic or a Wiki dedicated just for building the libraries or downloading already completed toolkits.

"I, myself, prefer to focus on using Qt and not building it. I let the pros at Qt or distro builders do that."

So do I! I want to use Qt not build it, but pros at Qt made a silly decision to distribute Windows binaries without "-opengl desktop" option, perhaps their rationale was the fact that windows does not by default provide latest OpenGL drivers, so they wanted to make life of Qt OpenGL developers "better" by providing binaries using that ANGLE.

However, pros building Qt failed to realize the fact that building the Qt is way more complicated than downloading the OpenGL drivers for your system.

Hopefully the Qt people noticing this thread will try to fix it and redistribute binary installation of Qt for Windows with -opengl desktop option. Otherwise its just plain stupid

But isn't it not dependent on me? In other words, should I just start searching for the file name "QByteArray" and just correcting each source file to point to it? That rather sounds not good to me though...

And another question, now regarding those attributes, I opened that OpenGL Boxes example now in the Installed QtCreator, and put this line right before instantiating QApplication:

setAttribute(Qt::AA_UseDesktopOpenGL, true);

And got the rrror:..\boxes\main.cpp(114): error C3861: 'setAttribute': identifier not found
